About the Staccato C & C2 3.9″ Bull Barrel by DPM Systems:
DPM Mechanical Recoil Reduction System for Staccato C2 3.9″ Bull Barrel – 9mm
The Spring Plug (Bushing) must always be installed when the DPM Recoil Rod and springs are used.
The spacer is an optional use and provides +1.5 lbs (approx.) to the total force of the system for each spring.
The 2 black coated springs have wire diameter 1.1mm and are stronger (heavier) than the 2 silver and gold coated springs with wire diameter 1mm.
**As we lead the evolution of recoil reduction technology, products may change versions (new design with different springs, with or without plugs, washers, etc.) without any prior notice.**
